The cultivation of encapsulated S. cerevisiae in NaCS-PDMDAAC polyelectrolyte complexes was studied. The results showed that the encapsulated microorganisms had the same growth trends as in its free cell culture and, thus, NaCS-PDMDAAC microcapsules were suitable for the encapsulation of these biological substances. The encapsulated S. cerevisiae cells were fermented sequentially for 16 batches. The highest cell density in the capsules reached 2.64 x 10(10) cells mL(-1) and the ethanol concentration was 47.0 g L(-1). A model of the cultivation of the encapsulated S. cerevisiae was developed.
研究了在NaCS-PDMDAAC聚电解质复合物中包封酿酒酵母的培养情况。结果表明,包封的微生物具有与其游离细胞培养相同的生长趋势,因此,NaCS-PDMDAAC微胶囊适用于这些生物物质的包封。对包封的酿酒酵母细胞进行了连续16批次的发酵。胶囊中的最高细胞密度达到2.64×10(10)个细胞 mL(-1),乙醇浓度为47.0 g L(-1)。建立了包封酿酒酵母的培养模型。
